MicroAutoBox from Dspace is a programmable prototyping control unit for function development, now available in a new hardware version with a 300MHz processor.
Thanks to its high performance and convenient programmability, MicroAutoBox is already being used successfully by many automotive manufacturers and their suppliers.
The 300MHz processor increases the speed by 10-30%, depending on the application, compared with the previous 200MHz version.
Programs and models developed for the earlier MicroAutoBox can run on the 300MHz version exactly the same as on its predecessor - without having to be recompiled.
MicroAutoBox's compact dimensions and shock resistance mean it can be installed practically anywhere in the vehicle.
During function development, it performs the tasks that will later be done by the electronic control unit (ECU).
MicroAutoBox boots itself just like a production ECU.
It provides real-time hardware for testing complex controller functions and automotive-specific signal conditioning, which can also be adapted to customers' requirements.
Programming is done graphically from MATLAB/Simulink, eliminating time-consuming handcoding.
MicroAutoBox comes in a compact aluminium housing that contains the real-time hardware with a 300MHz PowerPC, local RAM, timer and 16Mbyte Flash EPROM.
The flash EPROM is used for recording measurement data on the flight recorder principle.
The I/O on MicroAutoBox provides A/D and D/A convertors, connection to the CANbus, digital I/O and an interface to existing ECUs.
For program transfer and data evaluation, a connection can be set up to a PC or notebook on an Ethernet, PCMCIA or ISA basis.
In addition, Dspace also offers extensive software support for convenient programming of MicroAutoBox and for measurement data evaluation.
It will also shortly be possible to control direct current motors.
